Реверс-инжиниринг стриминга FC2: Как построить высокопроизводительный загрузчик на базе HLS и FFmpeg.wasm
The article discusses the development of a high-performance downloader for FC2 Video using HLS and FFmpeg.wasm. It highlights the challenges engineers face in reverse-engineering streaming protocols and the advantages of client-side processing. The solution leverages WebAssembly to optimize video downloading while maintaining user privacy and data integrity.
- ▪FC2 Video uses HLS for streaming, which involves a master playlist and multiple media playlists with encrypted segments.
- ▪The downloader operates entirely on the client side, avoiding traditional server-based processing to enhance privacy.
- ▪WebAssembly allows heavy media operations to be performed directly in the browser, ensuring that user data never reaches external servers.

Однако для инженеров, работающих с такими платформами, как FC2 Video, это превращается в квест по деконструкции протоколов Adaptive Bitrate Streaming (ABS) и манипуляции бинарными данными непосредственно в рантайме браузера.
